Answer:
117.5
Step-by-step explanation:
y= 3.5x + 30, where x = his number of toys sold
y= 3.5(25) + 30
y= 117.5
If he sold 25 toys then his expenses would be $117.5
What is a linear function?
A linear function is given by y = mx + b, where m is the constant rate of change and 'b' is the value of function y when x = 0
For given example,
Andre pays $30 to rent the booth and the materials for his toys are $3.50 per toy.
⇒ b = $30
⇒ m = $3.5
So, the linear function for given problem would be,
⇒ y = (3.5)x + 30
here, x represents the number of toys sold
y represents the Andre's expenses
Now, we need to determine his expenses if he sold 25 toys.
Substitute x = 25 in above linear function,
⇒ y = (3.5 × 25) + 30
⇒ y = $117.5
Therefore, if he sold 25 toys then his expenses would be $117.5
